Holden is trying to tempt customers to buy its new imported Commodore and Equinox SUV with a seven-year warranty.

The Aussie brand is struggling to draw buyers into showrooms following the closure of its local manufacturing operations, with sales dropping by almost 20 per cent so far in 2018 compared to the same period last year.

To counteract the slide, and showcasing the confidence Holden has in its new fully-imported range of vehicles, it is matching Kia's benchmark seven-year warranty period - with roadside assistance for the same duration - on all new Commodore and Equinox models sold in March.

Backing that up, all other Holden models, including the Astra hatch and sedan, Barina and Trax, will come with five years coverage with roadside assistance, while the Colorado ute (pictured) and Trailblazer SUV extend that with the added incentive of free servicing for the first three years, potentially saving owners thousands.

To clear existing stock in dealerships across the country, all 2017-plated vehicles - either new or demonstrator models - are eligible for the five-year warranty and free servicing offer.

Holden is putting on a brave face, saying the incentives highlight how confident the company is with the quality and engineering of the vehicles.

"We've got a laser-like focus on providing our customers with peace of mind when they buy a Holden, and with extended warranties across the range and world-class new products, now is a great time to buy a Holden,” said Holden's Marketing Director, Mark Harland.

“We want more and more people to come and take a look at just how good these vehicles are and experience some of the great engineering work from our talented engineers – our new seven-year warranty on Commodore and Equinox shows just how confident we are.”
